T all to 710m it may comer-a Be it known that I. FREDERICK lV. Larson, acitizen of the United States, and residing at Baltimore city, State of lilaryland. have invented certain new and useful lnprovements in Space-Band hilcchanisnn which the following is a specification.

This invention relates to space baud mechanism for typographic machines particularly machines oi the kind disclosed in my copending; application Serial No. 222,760 filed March 15, 1918, oi? which the present application. 18 a division. it is the aun oi the invention to provide space band mechanism to which the space bands are (lGllCQYGtl and from which the hands may be easily and positively released for use in assembling; a line of matrices and space bands.

In the drawings accompanying; this specification and forminga part thereof.

Figure l is a front elevation partly broken away of a space band magazine. this I? also illustrating the arrangement or". v mechanism for releasing the hands trointhe 2 5 magazine;

Figure 2 is an enlarged view partly in section of the mechanism shown attliie lower portion of Figure 1;

Figure 3 is a sectional view on the line 3 3-3 of Figure 1; and

Figure l is a sectional View on the line l-l of Figure 3. lt will be understood that the space band mechanism of the present invention is arranged in a position on the machine to receive the space hands from an assembled line after the casting operation and after the matrices have been separated from the space bands and it will be further understood that suitable means (not shown) are provided on the machine for delivering the space bands to this mechanism.

In the drawings the numeral 10 represents generally the magazine into which the space bands are delivered, this magazine at its up per side being provided with spaced rails 11 upon which the ears of the space bands restas they enter and lie within the mag zine. These rails, as shown in the draw 15; the space bands are delivered to the magazine they will slide by gravity down the inclined portion of the rails 11 and the "foremost one will rest against the wall of the chute 12 down which the space bands fall when released.

rom the chute l2 shown ice being; sufiicieut to permit :the ears of the space bands to pass as they forms a stop or dctcnt which is positioned to contact with the lower ends oi the space hands as they enter the n'iaganine. This detent and the lower end of the rails 11 are arranged that the space hands in the mag -a zine will be held in an inclined position shown in the drawing. the foremost space band resting at its lower end against the detent and at its upper end against the wall of me chute 12. The upper surface oi the hlocl: l2. .'.nc.lined at and will he understood that 'when the space bands are lii'itc d orer the detent lthllilP/v w l slide down this inclined portion to a vert I nosi on enter the ch The surface 16 or r-ne block 1.3., or that a end the rails are spaced a lower ends 0:! the space in ids adapted to rest. also inclined and substanciallv parallel to the position takenbv the space hands resting in the ar line. pusher or lifting: devi it? is slidahlp ieuinzed on the surface 16 of the block 13, pusher lacing; arranged in a dovetail. guideway formedin or secured to the block 13. The upper end of thepusher is provided with an inclined surface at 18 which with the inclined uriace 15 of the hloclr 13 when the pusher s elevated. The upper end of the pusher s also provided with a smal lip or proiec Lion 19 which is ada ted to enter a' reccss in the forward side 0. the next to the foremost space hand where a group of space bands are rest ng aga nst the detent l, the purpose of this linger bei i to ensure that t .,r will raise the "foremost space band usual space key of the keyboard of the machine. The pusher is normally held in its lower position by a coiled spring as operatively connected to the rocker 20.

It will be understood from the foregoing description that as the space key of the machine is operated. the pusher 17 will be raised, thus lifting the lower end of the foremost space band above the detent 1a where upon such space band will-slide down the inclined surface 15 of the block 13 and through the chute 12 into the'line assembling receptacle of the machine. This means for releasing the space bands by lifting the lower ends of the same acts quickly and positively and has been found to be simple, quiet and effective in operation.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is 1. In a. mechanism of the kind described, a space band magazine, means for supporting space bands at their upper ends in said magazine, an abutment engaging the lower end of the foremost space l and of a group for holding the same normally in inclined position, said abutment having an inclined front surface arranged substantially paral lel to the space hands when the sane are normally positioned against the abutment, a lifting device slidably mounted on said inclined surface of the abutment and adapted to lift the foremost space band and permit the same to swing over said abutment, said device having projection on its upper end for separating the front space band of a group from the one adjacentthereto.

2. In a mechanism of the kind described, a space band magazine, inclined rails at the upper part of the magazine upon which the sis of space bands are adapted to rest, an abutment at the lower part of the magazine against which the lower end of the foremost space band of a group rests when in normal position in the magazine, said abutment being so positioned that the lower ends of the space bands resting against the same will be held rearwardly of the upper ends thereof, said abutment having an inclined front face arranged substantially parallel to'the position taken by the space bands resting in the magazine, a lifting device slidably mounted on said front face of the abutment, said lifting device having a projection on its upper end adapted to be inserted between the front space band and the adjacent one upon upward movement of said lifting device, and means for moving said lifting device.

3. In a mechanism of the kind described, a space band magazine, inclined rails at the upper part of the magazine upon which the ears of space bands are adapted to rest, an abutment at the lower end of the magazine against which the lower end of the foremost space band rests when in normal position in the magazine, said abutment being positioned to hold the lower ends of the space bands rearwardly of the upper ends whereby the same occupy an inclined position in the magazine, said abutment having an inclined front face against which the space bands are adapted to lie in an inclined position, lifting device slidably mounted on and movable parallel with said inclined face of said abutment, and means for moving said device.

In testimony whereof I affix my si nature.
